Z,
I'm not going to get to everything in your previous post, we've already covered a lot of it in previous posts.
I will say that when I said 'I also doubt that [that is possible]', I meant the 2.5g launch, not necessarily the super fast acceleration times. Given the right surface, who knows, although those last 3 tenths will be hard won (and my bet is still on 4WD electrics).
I'll also say, if it wasn't obvious from context, that the blue A-T curve I posted corresponds to a run of exactly 3.30s. (the red one that's taken from your V-T diagram actually takes a car from 0.3m to 75.3m in 3.15s, so it's not completely apples to apples, the final speeds were very close though, 31 vs 30m/s, taken from Zürichs run and your graph respectively).
I do think that A-T diagrams are interesting, as they say a lot more about what forces act on the car at any given time, and you can differentiate much clearer between the theoretical runs you and I proposed.
V-T diagrams tend to look pretty similar pretty quickly.
We're in agreement on most of the mechanics, and the usefulness of various tools.
However, one of the most effective Toothless Hillbilly tricks (dramatically increasing mu by putting glue on the track, https://www.youtube.com/watch?v=1VMb0fmalqo, who needs Fz if you have that) is unfortunately not transferable to FSAE.
I think that means we won't see 2.5g launches, no matter how much dynamic-R% you manage. Electric 4WD's already put 100% of their Fz on the driven wheels. Transferring a larger portion of that to the rear axle shouldn't all of a sudden get you from 1.5g to 2.5g, especially if you take tire load sensitivity into account. I don't we're going to agree on how much of that remaining 1g can be bridged by the dynamic effects of pitch inertia on cars lifting their front wheels.
I'll be on the lookout for blackberry bushes, thanks for your encouraging words on that topic.
Thijs

They have lots of fun doing drag runs in their 1100hp FWD cars, averaging 1,7+g over the first 20 meters, suggesting to me that raw mechanical grip has as much to do with why dragsters accelerate faster than FSAE cars, as does how you load your driven axle.
